Taking star shots It's not going to make any real difference to exposure - just capture more stars, making the starfield in shot look denser than with a zoomed in lens. Are you using a tracking mount? Found a great youtube vid here includes a diy tracker - https://www.youtube.com/watch?v=vg3a0I0duMI

Hi,
I'd already decided to replace the filter with a Hoya, which I ordered yesterday.
I didn't see any plus point regarding the filter when I bought the lens, other than this cheap filter had been fitted from new and had therefore probably protected the lens.
I have been quite unimpressed with the lens for day light shots and had kind of assumed it was down to the cheap filter.
For star photography I am quite pleased with the lens, just wish I didn't have to use such high ISO, which results in so much post processing...
I'm not using a tracking mount. I'm purely a novice and stare at the sky until I can see things!
I tend to use 3200 ISO and a 20 second exposure.
These are the two most recent results using my "new" lens, both taken with full moon which isn't ideal..
I will definitely check out the video you linked to tomorrow, but now I have to go to bed!

Hi, I understand that, I was out with my fiance and her camera was completely unaffected, only mine misted up. It wasn't cold out either.
I assumed that the cheap filter that came with the second hand lens was to blame. I wondered if the cheap filters weren't anti fog coated... (I have no idea if any filter has anti fog coating!)
